This module executes a command on a received trigger pulse.

Configuration

- name: my_command
  so_file: libmodule_command.so
  config:
    command: /path/to/stop_trace.sh
    [ stop_trace: false ]
    [ allow_concurrent_executions: true ]
  trigger:
  - dev_name: jitter.new_maxever.trigger
    direct_mode: true
  power_up: op
  depends: timer

command : This specifies which command to execute. In our example this will stop the currently running trace process. (if set to special value `stop-trace` no command will be executed, only tracing is stopped, see below)

stop_trace : When set to true `0\n` will be written to `/sys/kernel/debug/tracing/tracing_on` before executing a shell command.

allow_concurrent_executions : when set to `false` (the default) the command will only be executed again when an earlier execution has finished.

The module needs to be attached to a trigger device.
